    ICD-10-CM Code For Other Diseases Of Biliary Tract: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K83 includes noncalculous and other specified diseases of the biliary tract such as cholangitis not elsewhere classified, biliary strictures, and biliary cysts that affect bile ducts and related structures. These ICD-10-CM diagnosis codes are used to document clinical presentations involving inflammation, obstruction, infection, or structural abnormalities of the biliary tree, capturing organ involvement and clinical complexity. Accurate coding within the ICD-10-CM K83 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM K83: Other Diseases Of Biliary Tract Overview

    This code group includes diagnoses for noncalculous and other specified diseases affecting the biliary tract, including strictures, cholangitis not elsewhere classified, and biliary cysts. It targets the biliary system — bile ducts and associated structures — and reflects inflammatory, obstructive, or structural pathology. Accurate coding matters for appropriate claim adjudication and to ensure clinical records reflect the specific biliary condition affecting patient care.

    When to Use

    Use a code from this group when the clinical documentation identifies a specific noncalculous or other specified biliary tract disease such as cholangitis, biliary stricture, or biliary cyst. Select the most specific code that matches documented disease details, including laterality, complications, or associated conditions when applicable.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden onset right upper quadrant pain, fever, jaundice, and elevated liver enzymes after recent hospitalization for a laparoscopic cholecystectomy; imaging suggests a postoperative stricture or obstructive cholangitis of the bile ducts. The acute presentation with signs of biliary obstruction and possible infection prompts assignment of a code reflecting an acute biliary tract complication. Typical codes: K83.1, K83.2
    • A middle-aged patient with known chronic biliary dyskinesia experiences recurrent episodes of biliary-type pain after fatty meals without evidence of gallstones on ultrasound; hepatobiliary scintigraphy shows impaired gallbladder ejection fraction indicating functional biliary disorder. This chronic, noncalculous biliary dysfunction seen in outpatient follow-up leads to assignment of a code for an unspecified or functional disorder of the biliary tract. Typical codes: K83.9, K83.3
    • An older patient undergoing evaluation for painless jaundice is found to have a benign stricture of the common bile duct related to prior pancreatitis, causing progressive cholestasis and requiring endoscopic stent placement. As a complication/comorbidity causing biliary obstruction and cholestatic lab abnormalities, a code for bile duct stricture or stenosis is used. Typical codes: K83.5, K83.4
